.SH "NAME"
.LP 
\fBsslproxy.conf\fR \- Configuration file for SSLproxy
.SH "DESCRIPTION"
.LP 
The file sslproxy.conf configures SSLproxy, sslproxy(1).
.SH "FILE FORMAT"
The file consists of comments and options with arguments. Each line which 
starts with a hash (\fB#\fR) symbol is ignored by the parser. Options and 
arguments are of the form \fBOption Argument\fR.
.LP 
Structured proxyspecs are defined between curly braces. The opening curly 
brace should be on the same line as the ProxySpec keyword. The closing curly 
brace and option-argument pairs should be on a line of their own.
.LP 
The arguments are of the following types:
.TP
\fBBOOL\fR 
Boolean value (yes/no).
.TP 
\fBSTRING\fR
String.
.TP 
\fBNUMBER\fR
Unsigned integer.
.SH "DIRECTIVES"
.LP 
When an option is not used (hashed or doesn't exist in the configuration file) 
sslproxy takes a default action. If an option is defined outside any 
structured proxyspec, then it is used as a global default. If an option does 
not have a command line equivalent, -o opt=val option can be used to override 
it on the command line.
.TP 
\fBCACert STRING\fR

.TP
\fBCAKey STRING\fR
Use CA key (and cert) to sign forged certs. Equivalent to -k command line option.

Use URL as CRL distribution point for all forged certs. Equivalent to -q command line option.

site matches SNI or common names in the SSL certificate, the connection is 
passed through the proxy. Per site filters can be defined using client IP 
addresses, users, and description keywords. '*' matches all users. User auth 
should be enabled for user and description keyword filtering to work. 
Case is ignored while matching description keywords. Multiple sites are 
allowed, one on each line.
